How to Store Bearings Properly: Avoid Rust & Preserve Performance

• Temperature: Maintain a constant temperature (15-25°C). Avoid extreme fluctuations (condensation causes rust).
• Humidity: Keep relative humidity below 60%. Use dehumidifiers in warehouses—moisture is the biggest enemy of GCr15 steel.
• Cleanliness: Store bearings in a dust-free area. Avoid proximity to chemicals, corrosive gases, or metal shavings.

• Keep bearings in original packaging: Our bearings come in moisture-proof paper or plastic bags with anti-rust oil. Do not open until installation.
• Store horizontally: For large bearings (e.g., BA222-1SA with 222mm ID), place on flat surfaces to prevent deformation. Small bearings (e.g., 51101 with 12mm ID) can be stored in racks or drawers.
• Avoid stacking heavy objects: Stacking can damage the outer ring or cage—use separate shelves for different bearing sizes.

• Follow “First-In, First-Out": Bearings have a shelf life—even with proper storage, anti-rust oil degrades over time. Use older inventory first (our packaging includes production dates).
• For long-term storage (6+ months): Reapply anti-rust oil every 3 months. Rotate bearings 90° monthly to prevent permanent deformation of rolling elements.

• Inspect before use: Check for rust, oil leakage, or damage. Wipe off excess anti-rust oil with a clean cloth—do not use harsh solvents (they damage the GCr15 steel surface).
• Lubricate immediately: Even if the bearing is pre-lubricated, apply fresh grease matching your application (e.g., high-temperature grease for motors, heavy-duty grease for excavators).

Pro Storage Tip: For large quantities, use airtight storage containers with silica gel packets to absorb moisture. KESILE offers custom storage solutions for bulk orders—contact our sales team for details.
